What’s the pressure sensor on a Jeep Grand Cherokee?
The pressure sensor is a 5-volt reference sensor. When the wheels are not rotating, voltage around 0.6 V is normal. As the wheels begin to speed up, the voltage should increase proportionately. If the voltage does increase, then the pressure is increasing as it should – this should be verified with a pressure gauge.
